As the brains behind a hydroponics farming system in rural Kenya, 17-year-old Jefferson Kang'acha struggled to get noticed but he now expects the youth climate movement led by Greta Thunberg to bolster other young people on a mission.

Kang'acha, a computer technology student, decided to apply technology to farming when his parents were hit by another drought and he came up with an automated hydroponics unit built from recycled waste and plastic bottles.

After his first unit produced 2 tons of tomatoes, he founded the Eden Horticultural Hub, a social enterprise that now runs four hydroponics systems in his home town of Limuru to supply the local community and lunches to 1,500 school pupils.
